Biography
Yu Jianshan was a member of the Templar Order, joining them in 1634 when they decided to support the Manchu in taking power in China. Promised a high rank and title, he was initiated and became a general of the Manchu Qing Dynasty. He carried out a brutal military campaign against the Choson Empire of Korea in 1639 and forced them to surrender, bringing Korea under the control of the Templars. His unparalleled successes on the battlefield drove the Manchu leadership to consider him a great general and a possible heir to their dynasty.

However, his Templar plotting ended in 1640. Jianshan planned an invasion of the Ming Empire through the Shanhaiguan Pass, and led an army of Manchu warriors to subdue the Ming. However, he was shot in the chest with a crossbow bolt by Ma Jianguo of the Assassin Order as he tried to rally retreating units, and fell from his horse. Jianguo then charged up to him and stabbed him in the chest with his hidden blades, finishing him off.
